The technique of synthesis of polymethylmethacrylate -cadmium sulfide nanocomposites involving precipitation of CdS nanoparticles from polymethylmethacrylate solution in methylmethacrylate monomer with its subsequent polymerization is presented. The influence of molecular polymer mass and polymerization conditions on the dispersion stability is discussed. The spectral-luminescent properties of nanocomposites are investigated. A difference between the spectral-luminescent properties of the surface composite layer and the nanomaterial bulk, connected with redistribution of particles with higher degree of imperfection closer to the surface during polymerization is revealed.
